if it's just for the animation, it's a 5/5
but now... you painted the bricks, and for me, this is modding, and I don't like it (anymore)
Also, you painted white minifigs bloody, and I can promise you that it'll be a pain in the butt to get the color off again.
I once, as I was younger, painted some figs bloody and the color is still visible, and I hate myself for that now...
